"... Did I not make you swear by the Lord and worn you...?" At that time you said to me, 'What you say is good, I will obey.' Why then did you not keep your oath to the Lord and obey the command I gave you?"
1 Kings 2:42-43
Why waste your precious time and the precious time of others promising things that you have no intention of following through with?
Hence, if you don't mean it, DON'T SAY IT.
